Facet Mapping Apr 24, 2026

New Facet Mapping: All WordPress Post Columns, Postmeta Keys and WooCommerce Taxonomies Mappable
Every indexable WordPress source is now mappable — core post columns (post_title, post_content, post_excerpt, post_date, post_author, …), ALL postmeta keys (the underscore-prefixed WooCommerce core fields like _price, _sku, _stock, _thumbnail_id are now visible — previously hidden as "private"), every public taxonomy, all WooCommerce pa_* attribute taxonomies, plus synthetic featured_image_url and gallery_image_urls aggregates.

Drupal Module Apr 24, 2026

New Opensolr Search for WordPress 1.0.7 Adds the Lexical Only Search Mode
Opensolr Search for WordPress 1.0.7 — adds the Lexical Only search mode, matching the Opensolr admin and Drupal module. Explicit opt-out from vector: no embedding API call is made, search runs through the lexical edismax path. The Minimum Relevance Score slider auto-zeroes the moment the radio is picked (backend enforces this on save and at query time as well). Yellow note in Search Mode explains the coupling.

New Opensolr Search for Drupal 3.5.0 Adds the Lexical Only Search Mode
Opensolr Search for Drupal 3.5.0 — adds the Lexical Only search mode, matching the option in the Opensolr admin. Skips the embedding request entirely and runs pure lexical search. When selected, the Minimum Relevance Score is auto-zeroed (on save and at query time) so results aren't filtered out by a hybrid-calibrated threshold. Same feature across the stack — Opensolr admin, Drupal module, WordPress plugin.

New New Lexical Only Search Mode Skips Embeddings for Pure BM25 Ranking
New Lexical Only search mode in Search Tuning → Search Mode. Explicit opt-out from vector — no embedding API call is made, search runs straight through the lexical edismax path. Useful for deterministic BM25 ranking, avoiding embedding API latency, or users on plans without vector who want explicit control instead of the implicit server-side fallback. When selected, the Minimum Relevance Score slider auto-zeros itself (that threshold is calibrated for the combined hybrid score; a positive value would filter out every result in pure lexical mode) and a yellow note explains the coupling.

Opensolr Search for WordPress 1.0.5 — adds the Minimum Relevance Score slider to Search Tuning, matching the feature in the Opensolr admin and Drupal module. Drops low-scoring hybrid hits from results and facet counts, cleaning up catalog and content searches. Slider is in 0.1 increments, default 0.3.

New Search Operators Help Panel: Phrase Match, Required, and Excluded Terms
New Search Operators help button next to the Search bar. Opens a panel explaining "phrase match", +required, and -excluded operators with examples and a note on why they matter in hybrid search. Users can now refine queries like +laptop "13 inch" -refurbished and cut through semantic noise instantly.
New New Minimum Relevance Score Slider Filters Low-Scoring Hybrid Search Hits
New Minimum Relevance Score slider in Search Tuning. Drops hits whose combined lexical + vector score falls below the threshold, cleaning noise out of facet counts and result totals. Essential for hybrid search on catalog-style content — without it, numFound balloons to the entire filter set and facet counts pick up docs the user would never consider relevant. Slider moves in 0.1 increments, default 0.3, 0 disables.

Analytics Apr 21, 2026

New Query Analytics: Export Every Dashboard Table to CSV
Export CSV from Query Analytics — every table in the Analytics Dashboard (Popular Queries, Latest Queries, Path Distribution, Queries Over Time, Per-Server Stats) now has a green Export CSV button. Downloads are UTF-8 BOM-encoded for Excel compatibility, and the Latest Queries export respects your active filters (search, HTTP status, IP address).
